Tax Planning Under Pressure: The Impact of Carbon Emissions Management Post‐Paris Agreement

Accounting &Finance, EarlyView.
ABSTRACT We examine how the Paris Agreement affects corporate tax planning across a global data set. We find that emissions‐reducing firms are associated with higher levels of tax planning than nonemissions‐reducing firms. The effect is stronger for firms facing tighter cost pass‐through constraints, such as operating in more competitive markets, with ...

Exact Analytic Solutions for Stellar Wind Bow Shocks

Astrophysical Journal, 1996
Stellar wind bow shocks have been seen in association with a wide variety of stellar objects, from pulsars to young stars. A new solution method is presented for bow shocks in the thin-shell limit, stressing the importance of the conserved momentum within the shell.

Polarization Signatures of Bow Shocks in Stellar Winds

EAS Publications Series, 2015
Bow shocks around massive stars provide important information regarding the motion of the star, the stellar wind properties, and the density of the surrounding interstellar medium. We use a Monte Carlo radiative transfer code to investigate the polarization created when photons from a central star scatter from electrons or dust grains in a surrounding ...

Bow Shock Structures Near Young Stellar Objects

, 1988
We have obtained narrow band CCD images of several Herbig-Haro objects resembling bow shocks. As predicted by bow shock theory, we find that the region of highest excitation coincides with the apex of the proposed shock.

Collision between dissimilar clouds: stability of the bow-shock, and the formation of pre-stellar cores

Monthly Notices of the Royal Astronomical Society, 2010
We use smoothed particle hydrodynamics (SPH) to simulate a head-on collision between two physically dissimilar clouds, and investigate the dynamical stability of the post-collision bow-shock. The shock-front appears susceptible to a number of hydrodynamical instabilities such as the Kelvin―Helmholtz instability, the Rayleigh-Taylor instability, and the
